The results show the tons of tiny and discontinued watersheds. I went through each steps and found the stream definition results are coming with a lot of short pieces. What is the reason for this kind of results? Any suggestions?

Using fdr instead of fac will do this kind of thing. Confirm that you ran fill sinks properly and that the right layers are used in subsequent processes.</SPAN></BODY></HTML> Mon, 19 Mar 2012 15:07:56 GMT https://community.esri.com/t5/water-resources-questions/geohms-terrain-preprocessing/m-p/529967#M2736 MarkBoucher 2012-03-19T15:07:56Z
